I installed my XT Kartboy short shifter on Wednesday and ever since then I have been hearing a strange metallic scrubbing noise. Initially I thought it was the wear indicator on my brakes but after listening to it more while driving today I think it is more related to the drivetrain. It is a faint noise that sounds like something is rubbing another something that is turning. It becomes more pronounced when stepping on the brakes. The thing is, it changes when messing with the shifter. I can pull back on the shifter when in 4th and the sound stops. This tells me it must not be brake related. I am wondering what the heck it is. Could something be rubbing in the tranny or could something be rubbing the drive shaft just under the shifter. I don't know but I plan to investigate a bit more. Anyone else having any similar experiences?
